Method of improving the corrosion resistance of aluminum alloys and products therefrom

摘要

A method of improving the corrosion properties of an aluminum alloy product containing solid solution alloying elements includes the step of rapidly quenching the alloy product after it has been heated or hot deformed so as to maintain the alloying elements in solid solution to avoid microsegregation of the solid solution alloying elements and minimize preferential sites for corrosion onset.
